# Hensel Mi_ZR_4 enclosure extension frame Canonical URL: https://eloragrid.ai/objects/ga-mi-zr-4-aa668197be0f Publisher: Elora Grid Updated: 2026-10-29 Lookup label: Mi_ZR_4 Drawing use: GA Reference families: Manufacturer Mi_ZR_4 enclosure extension frame arrangement: mounting, interface and service-space coordination. ## In plain English ### What it does Mi_ZR_4 is the drawing identifier for enclosure extension frame in Hensel's ENYMOD Mi enclosure and distribution-system STEP collection. An extension frame forms part of a selected enclosure assembly. Its mating surfaces and the extra interfaces it introduces need to be shown alongside the adjoining enclosure components. ### A simple example For example, in a microgrid installation with a distribution enclosure configured with a selected extension frame, use the Mi_ZR_4 reference to coordinate base-to-frame and frame-to-cover interfaces. Show the neighbouring equipment and the connection route so the installer can understand the intended arrangement. ### What the drawings help you do Use the reviewed native drawing identified as Mi_Zwischenrahmen/Mi_ZR_4.stp for the exact physical details. Locate the named file in its original manufacturer archive. Manufacturer drawing previews are shown only when an exact approved source is available. Any illustrative 3D view is a separate concept and is not to scale; use the selected manufacturer documents for dimensions, ratings and installation details. ### Before using this reference - Match Mi_ZR_4, the native drawing identity and the project equipment schedule. - Identify every component in the selected enclosure stack. - Coordinate base-to-frame and frame-to-cover interfaces with neighbouring equipment. - Confirm the current manufacturer installation instructions, selected revision and any required mounting or clearance details. ### Terms - Drawing identity: The named manufacturer drawing used to identify the intended physical configuration. - Interface: The place where this part mounts, connects or meets another selected part. - Service space: The area needed to reach, disconnect or remove the selected equipment as instructed. Concept diagram: Identify Mi_ZR_4 → Coordinate enclosure extension frame → Confirm the selected installation A practical coordination sequence for this named equipment reference. It is not an electrical connection diagram. - [Hensel ENYMOD Mi enclosure and distribution-system STEP official CAD source](https://www.hensel-electric.de/de-de/service/downloads/digitale-produktdaten/3d-step.php) ## What it represents Mi_ZR_4 is the drawing identifier for enclosure extension frame in Hensel's ENYMOD Mi enclosure and distribution-system STEP collection.

A drawing in the same collection is not automatic evidence of compatible terminals, mounts or electrical performance. ## Information to show or reference - Match Mi_ZR_4, the native drawing identity and the project equipment schedule. - Identify every component in the selected enclosure stack. - Coordinate base-to-frame and frame-to-cover interfaces with neighbouring equipment. - Confirm the current manufacturer installation instructions, selected revision and any required mounting or clearance details. ## Important distinction This reference concerns the named Mi_ZR_4 drawing and its enclosure extension frame role. A drawing in the same collection is not automatic evidence of compatible terminals, mounts or electrical performance. ## Facts - Manufacturer source: Hensel - Native drawing identity: Mi_ZR_4 - Reviewed equipment role: enclosure extension frame - CAD scope: ENYMOD Mi enclosure and distribution-system STEP - Preview scope: Source-matched manufacturer drawings where available; illustrative 3D is separate and not to scale ## Public references - [Hensel ENYMOD Mi enclosure and distribution-system STEP official CAD source](https://www.hensel-electric.de/de-de/service/downloads/digitale-produktdaten/3d-step.php) — Hensel.
